High Winds

Protecting farm buildings from severe winds

High winds can damage farm buildings. The following procedures are recommended to help protect buildings during severe thunderstorms:

Securely close all doors and windows. If it appears that strong winds may break fasteners and hinges, provide additional reinforcement. Nail doors and windows shut, if necessary. If the building is tight, open windows slightly on the side away from the wind to help equalize pressure.
Nail plywood or boards over large windows and windows with weak sashes.
Brace large barn doors and weak walls. Use interior braces on the windward side, and exterior braces on the side away from the wind. If you are uncertain about the direction or the wind, use both interior and exterior braces. Place braces on the reinforced section of the door or wall to distribute the bracing effect over a larger area.
Check that roof rafters are securely fastened to the wall studding. Use 2" X 2" metal plumber's straps or 2" X 6" knee braces to secure rafters, if necessary.
Check metal roofing and siding for loose nails. If nails don't tighten when hammered back in, pull them out, use a #12 or #14 metal screw to fill the hole, and renail 3 to 4 inches away; eaves should be nailed every 5 inches.
Do not use heavy machinery to anchor small buildings. Replacing machinery could be more expensive than replacing a building.
Install the tie rod "X" braces in long buildings if hurricane is predicted.
